Serial No. 606,690.

To all whom it may concern.:

Be it known that I, ARTHUR BnANDEs, a

i citizen of the United States, residing at Cincinnati, county'ofHamilton, and State of Ohio, have invented certain new and usefulImprovements in Friction-Locked Hinges;I

bland I do declare the following to be a clear, i full, and exactdescription of the invention,

attention being called to thedrawin which v,accompanies this applicationand orms a part thereof. I .Q This 'invention relates to hlnges of thekind where one Iof two parts connected by the hingeis yieldingly held inan angular position to-which it has been adjusted Vwith .reference tothe other part, by frictional rc sistance which opposes the freemovement of the adj usted part.

ticularly .pointed out in the claims at the end thereof, will be found afull descriptirm of my invention, together' with its operation,

u parts and construction,.which latter is also illustrated in theaccompanying drawing, in

. LWhich Figure l, shows the hinge in vertical, centralse'ction. Fig. 2,is a side-view ot' one of the two complementary hinge members. Fig. 3,is a \f'ertical section of the other complementa r y hinge-memlier. Fig.4, is a frontview ot the hinge. Fig. is a front-view :if thehinge-member shown in Fig. 2.

T he hinge is described and illustrated in cormection with thewindshield of an automobile. These devices consist usually of astationary part A and of a lapB movably connected to it ,by means ofhinges, there be ing one hinge at each edge of the shield. The movable,flap may be folded lup flat against the stationary part 'of the shield,or adjusted to any desired angle. It is held in such position byfrictional resistance provided in the hinges and which opposes the freemovement of one of the complementary hinge-n1embers on the other member,but

yields when a certain force is applied.

* In the drawing, C indicates one of the complementary hinge-members andD indicates the othpr member. One of these mem bers, C in t is case, isthe stationary member of the hinge., itbeing provided with a tla'nge 9where'py-1t is mounted upon the Vfitting hub 17 against it accordingly.

frame a of the stationary shield part A. This flange 9, supports a basel0 from which the hinge-pin c, rigidly connected, projects outwardly. 11is a stud which also projects from this base butvperforms no functionwith reference to the hinge, serving merely as a means to permitconnection of a brace l2 which sustains the wind-shield' onlthe auto.All of these parts of member Cas described are by preference containedintegrally in one piece as shown in Fig. 2. The other hinge-member Dwhich is the movable member of the hinge, consist substantially of a hub13, open on its front-side and conically recessed. It is centrallyperforated in the deepestpart of the recess at 14, the opening beingfitted to receive hingefpin c, which extends through this opening andprojects into the recess. An arm l on this member attached ly means of aflange 15 to fra-me b of the movable flap B of the windshield completesthe hinged connection of this flap to the stationary part of thewind-shield.

Frictional resistance is provided to prevent the movable member `fromswinging freely on hinge-pin c, and to hold this member in any positionto which it has been moved by flap It (.fonnected'to it, the objectbeing to hold this flap in any position to which it has been adjustedwithout requiring any special lmking-means. This resist- 'ance is sograded as to hold the flap in any position under conditions considerednormal for a particular purpose, but permitting it to' yield when acertain force is applied. This frictional resistance is obtained bymeans of friction cone 16, fitted into the conical recess ot hub 13, soas to be in contact with the surface of this recess and provided with ahub 1.7, whereby it is mounted upon the extended parl: oi pui c. It isheld on this latter to prevent it from following hinge-member D in arotary direction by any suitable means as for instance by a pin 18 onhingepin c which extends into a slot 19 in hub 17 ol the cone. Suchrotation may also be prevented by shaping the extended part of pineotherwise than round and by In whatever way this is done, it is donc ina manner which permits the cone to have full and 'unrestricted contactwith the surface within the conical recess in the hub and which contactis maintained by a spring 20 closes the recess in hub 13 against theoutside. The cap is screw-connected to be held in position as forinstance by a nut 22 which bears against the outside of it and is seatedupon a threaded extension 23 of hinge-pin c, which projects through acentral perforation in said cap. The frictional Contact of cone 16 ismaintained against wear by forcing it up on pin c and deeper into theconical recess, which is done by moving cap 2l farther into the hub soas to increase the action of the spring correspondingly. The opposingsurfaces, that within the conical lrecess and that of cone 16 in contactwith it,

may be roughened as for instance by corrugations to promote thefrietional resistance, or the recess may be contalned in a body ofpacking 24 of friction-promoting material like wood or fiber as shownAin Fig. 3.

It will be noted that no lateral strain tending to either spread orcompress the :trames of the shield, frequent cause of cracked glass anddue to the action or re-aetion of the springs, is transmitted to theseframes since the act-ion of the springs is entirely taken up in bothdirectionsand neutralized within the hubs and between them and shouldersQ5 at the base of pin c beyond which these ett'ects do not extend.

These hinges permit complete folding up of one part of the wind-shieldflatly against the other part and on either side ot the same, theparticular side being determined by 'positioning the hinges accordinglyHaving described my invention, I claim new:

l. lin a friction-locked hinge, the combination of two complementaryhinge-members, each provided with means for its attachment to the partsto be hingedly connectedv` one of the hinge-members comprising a hubhaving a central perforation which is diametrically enlarged on one sideof it to form a conical recess, a hinge-pin provided on the other memberwhich is fitted to the perform tion in the hub mentioned and extendsinto to the parts to be hingedly connected, one of the hinge-memberscomprising a hub having a central perforation which is diametricallyenlarged on one side of the hub to form a conical recess, a cap to closethisrecess, a hinge-pin projecting from the other member upon which thishub is mounted and which pin reaches into the recess ot the hub,

a friction cone contained within this recess,r f

a spring provided between the cap and this cone yto hold this latterwithin the recess, means to preventrotation of thefcone with the hub andmeans to adjust the position of the cap to regulate the action oi' thespring.

3. In a friction-locked hinge for hinging the two parts of a wind-shieldto each other, the i combination of two complementary hinge-members, onebeing in form of a perforated hub provided with an arm eXtend.-

ing from it which terminates in an attaching Aflange for connection, toone of the parts et the wind-shield, the other member comprising a baseprovided with a flange for attachment to the other part of thewindshield and with astrid to permit connection to a brace and with ahinge-pin which receives the hub of the other hinge-member and therebycompletes the hinged connection between the two parts of the wind-shieldand means provided ont-he hinge-pin and in frirtional engagement withthe hub to retard free rotation of' this latter.

In testimony whereof, lf hereunto ai'iX my signature in the presence oftwo witnesses.
